Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 10006-1988 "Plastics - Film and sheeting -
Determination of the coefficients of friction". Compared with GB/T 10006-1988,
the main technical changes are as follows:
- Modify the scope (see clause 1; clause 1 of the 1988 edition);
- Modify the normative references (see clause 2; clause 2 of the 1988 edition);
- Modify the terms and definitions (see clause 3; clause 3 of the 1988 edition);
- Add the note "The coefficient of friction of films usually ranges between 0.2
and 1" (see note 1 to 3.4.2);
- Modify the principle (see clause 4; clause 4 of the 1988 edition);
- Add the test device requirement that "Either the sled or the test table can
be used as the moving part"; modify figure 1; delete figure 2 (see 5.1 and
figure 1; 5.1, figure 1, and figure 2 of the 1988 edition);
- Modify the naming, order of subclauses, and structure of the "Test
apparatus" (see clause 5; clause 5 of the 1988 edition);
- Add the test speed setting requirement of "500 mm/min±10 mm/min" (see
5.2.3);
- Add the requirement for checking the transition time when using the force-
measuring system of a tensile tester (see 5.2.4);
- Modify "Directly connect the sled and the load cell" to "The spring shall be
replaced by a rigid connection" (see 5.2.5; 5.6 of the 1988 edition);
- Add the overshoot requirement for the coefficient of friction (see the note to
5.2.5);
- Modify specimen requirements (see clause 6; clause 7 of the 1988 edition);
- Modify the conditioning (see clause 7; clause 8 of the 1988 edition);
- Add the general rules of test procedure (see 8.1);
- Modify the test procedure of "Film against film" and "Film in contact with
metal or another material" (see 8.2 and 8.3; 9.1 and 9.2 of the 1988 edition);
- Modify the calculation of results of static coefficient of friction and dynamic
coefficient of friction (see 9.1 and 9.2; 10.1 and 10.2 of the 1988 edition);
- Delete the requirement of "Significant figures for result calculation" (see
10.3 of the 1988 edition);
- Add a description of precision (see clause 10);
- Modify the test report requirements (see clause 11; clause 11 of the 1988
edition);
- Add "Preliminary precision" (see annex A).
This Standard, using translation method, is identical to ISO 8295:1995 "Plastics
- Film and sheeting - Determination of the coefficients of friction".
This Standard was proposed by China National Light Industry Council.
This Standard shall be under the jurisdiction of National Technical Committee
48 on Plastic Products of Standardization Administration of China (SAC/TC 48).

The previous edition of the standard replaced by this Standard was released as
follows:
- GB/T 10006-1988.
Plastics - Film and sheeting -
Determination of the coefficients of friction
1 Scope
1.1 This Standard specifies a method for determining the coefficients of starting
and sliding friction of plastic film and sheeting when sliding over itself or other
substances. This Standard is intended to be used for non-sticky plastic film and
sheeting (in the following text, referred to simply as "film") of up to 0.5 mm
thickness.
1.2 This Standard serves primarily for quality control. It does not give a
comprehensive assessment of the machinability on packaging or processing
machines since other effects, e.g. electrostatic charges, air cushion, local rise
of temperature and abrasion are, as a rule, involved.
1.3 The static frictional force increases as a rule, with the time the surfaces are
in contact. Therefore, to get comparable results, this time span is specified.
1.4 Slip properties are sometimes generated by additives in the plastic material.
The additives have varying degrees of compatibility with the film matrix. They
may bloom or exude to the surface and change the slip properties. Since these
effects are time-dependent, measurements on such films have to be related to
the age of the film.
